Manny and Brigitta Davison outside court
Maxine Davidson, 57, claims her mother gifted her the gems. But Brigitta, 80, “denies she made any lifetime gifts at all”, a pre-trial hearing at London’s High Court was told today.
The claim is part of a wider £17million battle for more than 300 items, including part of an “exceptional” £13million silver collection.
Brigitta and her property magnate husband Manny Davidson, 85 – who has a £600million fortune – are suing art consultant Maxine and their businessman son Gerald, 57.

But the children are counter-suing their parents for 180 items.
The “most significant aspect” of the siblings’ case is Maxine’s claim for the jewellery collection, according to lawyer Stephen Rubin QC. “Worn by Brigitta for many years,” he told the hearing, the jewels are valued at £3million, and “include an exquisite sapphire ring”.
The court also heard the children “excluded” their parents from Lyegrove House – next to Prince Charles’ Highgrove estate in Gloucestershire – which they had owned since 1993.
The parents lived there until 2011 when they moved to Monaco.
However, they claim there was a “clear understanding” they could return to Lyegrove when ever visiting the UK.

That remained their belief until they were “excluded by their children in 2015”, Mr Rubin said.

Maxine and Gerald claim the home was bought as a weekend retreat for all of them.
They also allege their parents removed art and antiques from their home in the south of France – moving them to apartments in Paris or Monaco.
The court case is due to start on April 25.
